Maybe the fact that BT have pulled out is the catalist for the increase in capacity for SAS as the BT website shows DUB-RIX and DUB-VNO as all via CPH with SAS.
I have read elswhere that the CO filght to IAD is to replace the second EWR flight which makes sense as both flights operated so close together. Why did CO never have the second flight leave DUB at say 1700 or 1800??
Any ways may be the DAA subvension subsidies are starting to kick in now
